      @lif I’m not sure on that, @wishmaster270 (Tom) would know more.

      The "E" in "Javascript" stands for "Easy"

          @lif Hi. Great you want to try one of my modules.

          Can you try installing a additional python system package with

          sudo apt install python3-rpi-lgpio
          

          I tried the scripts on my newly installed system with Bookworm and everything worked as expected.
          Maybe the missing package had been installed with something else I installed on my system.

              That’s strange…Can you try to start with a new, fresh virtual python environment and install the needed libs again?

              Remove old virtual environment:

              rm -rf /home/pi/MagicMirror/modules/MMM-Temperature/scripts/py-venv
              

              Install the needed system libs:

              sudo apt -y update && sudo apt -y install python3-venv libgpiod2
              

              Re-Create the virtual environment:

              cd ~/MagicMirror/modules/MMM-Temperature/scripts
              ./venvWrapper.py --verbose --venv-name py-venv --create
              

              Re-Install the libs:

              cd ~/MagicMirror/modules/MMM-Temperature/scripts
              ./venvWrapper.py --venv-name py-venv --install-libs adafruit-circuitpython-dht
              

              Run the test again:

              cd ~/MagicMirror/modules/MMM-Temperature/scripts
              ./venvWrapper.py --venv-name py-venv --run ./dht22
              

              If it fails again. Can you please provide the output of

              cd ~/MagicMirror/modules/MMM-Temperature/scripts
              source py-venv/bin/activate
              pip freeze
              deactivate
              

              The output should look something like:

                  @sdetweil Hi sam. My wrapper script will use the python binary in the virtual environment folder. This way the environment will be activated automatically.

                      The only difference from yours is mine is missing the second line.

                      Hope this helps

                        Hi,

                        I’ve gone through your procedure again and this time it works.

                        The only difference is that I run a python3 script to control screen blanking using a PIR before starting Magic Mirror, this time I didn’t start that script.

                        With the PIR script and MagicMirror running I get:

                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 23.5, "humidity": 53.7, "temperature_f": 74.30000000000001, "error": false}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 23.5, "humidity": 53.7, "temperature_f": 74.30000000000001, "error": false}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 0.0, "humidity": 0.0, "temperature_f": 32.0, "error": true}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 23.6, "humidity": 53.5, "temperature_f": 74.48, "error": false}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 0.0, "humidity": 0.0, "temperature_f": 32.0, "error": true}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 23.7, "humidity": 53.3, "temperature_f": 74.66, "error": false}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                        {"temperature_c": 23.8, "humidity": 53.2, "temperature_f": 74.84, "error": false}
                        pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ 
                        
                        

                        I can live with that.

                        Thanks for all your help
